Ham Radio setup for HF voice and Digital Modes

My FT-450D connecting to a computer running Ham Radio Deluxe for HF.
The computer is also connected to my FT-8800R and also is running uiview for APRS Igate operation.


Great Multi-band Antenna for 10-80 meters

I just installed a 43 foot ground mounted vertical at home. Have been having fun making contacts all over the world with it using only a 100 Watt tranceiver.

Below is an excellent discussion on how to make one really perform without the complexity of a remote tuner.

My favorite QSL card so far is from this station I contacted in Canada. A qsl card is a confirmation of contact that ham radio operators send each other.


ICCAD Talk on Parallel Computing

I gave a talk at ICCAD that became a bit controversial since there are a lot of theoretical possibilities for parallel processing, especially on special purpose hardware like GPU's, but from a practical standpoint things are quite different. As engineers we have to not just discover possibilities but make things work.
